一、
现在进行时态表示现在(说话瞬间)正在进行或发生的动作。
二、
主语+be(am , is , are)+现在分词(动词+ing形式)+其它
肯定句式:主语+be( am, is, are)+现在分词+其它.
否定句式:主语+be(am, is, are) +not +现在分词+其它.
一般疑问句:Be(am, is, are) +主语+现在分词+其它?
注:现在进行时在其构成形式中,be动词有人称和数的变化,即要根据主语选用am / is / are。Be动词分为单数和复数,am和is是表示单数,am只跟I搭配(除了I其余的单数都用is),are表示复数。
三、
now , at the moment , look , listen , It’s + 具体点钟 , at present , these days
四、
动词+ing形式叫做动词的现在分词,现在分词的构成方法如下:
1. 一般在动词后直接加上-ing。例如:work working, do doing, talk talking,drink drinking
2. 以不发音e结尾的动词应先去掉e然后加-ing。例如:write writing, skate skating
3. 以ie结尾的动词,变ie为y加-ing。例如:lie lying, die dying
4. 以重读闭音节结尾的动词,如果该单词末尾只有一个辅音字母,则应先双写该辅音字母,再加-ing。例如:put putting,
sit sitting , plan
要双写的动词一般满足下面三个条件:① 单词末尾的字母结构是“辅+元+辅”;② 上述结构中的元音字母发短元音;③ 单词末尾的音节重读。 例如: run running, begin beginning
五、
【例如】:
1.
They are not reading an English book.(否定句)
Are they reading an English book? (一般疑问句)
What are they doing? (特殊疑问句)
2.
He is not playing basketball on the playground. (否定句)
Is he playing basketball on the playground? (一般疑问句)
What is he doing on the playground? (特殊疑问句)
六、
何时使用进行时,简单地说,就是当句子出现现在进行时的判断标志词时(见第三 点),应该使用现在进行时。详解如下:
1. 当句中出现的表示时间的词是now, at the moment (此刻、现在)等时,表示句子要说明的是现在正在发生的事,动词应用现在进行时。
【例如】:
Linda's brother is watching TV in his bedroom now.
琳达的哥哥现在正在他的卧室里看电视。
We're far from home. What are our parents doing at the moment?
我们现在远离家,我们的父母此刻在干什么呢?
2. 当句中出现的时间状语是these days, this week, this month等时,如果句子所要表达的意义是在这一阶段正在发生的事,则动词应用现在进行时。
【例如】:
These days we are helping the farmers work on the farm. 这些天我们在农场帮农民们干活。
They're having a test this week. 这一周他们在进行一次考试。
Mr Cheng is visiting our village this month. 这个月程先生在我们村访问。
3. 在句中出现了Look, Listen, Can't you see? 等暗示词时,说明后面谓语动词的动作正在发生,该动词应用现在进行时。
【例如】:

看!玛丽亚和汤姆正在树下跳舞。
Listen! Our English teacher is singing the popular English song.

4. 注意根据上下文的暗示,句子的谓语动词可能应用现在进行时。
【例如】:
— Where is Mr Wang? — 王先生在哪儿?
— Oh, he is reading a newspaper in the office. — 噢,他正在办公室看报。
(问句询问王先生在哪儿,应说明他现在在哪儿,故答句应说明他现在正在做的事,用现在进行时。)
—Is that boy Jack? — 那个男孩是杰克吗?
— No. Jack is doing his homework in the classroom. — 不是,杰克正在教室做作业呢。
(答句中说明的杰克做作业的情况应发生在现在,应用现在进行时。)
